Description
Technical field
The present invention relates to a kind of stop valve, a kind of direct insertion angle stop valves.
Background technology
Angle stop valves opening and closing element is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along fluid
Centrage is for linear motion.The forms of motion of valve rod, has elevating lever-type (valve rod lifts, and handwheel does not lifts),
Also there is lifting rotation rod-type (handwheel is rotation and lifting together with valve rod, and nut is located on valve body).Stricture of vagina pipe ends
Valve is only applicable to standard-sized sheet and fully closed, does not allows to make adjustments and throttle.
But this kind of stop valve is required for rotation valve rod in opening-closing process, time long between valve rod and sealing member
Between spin friction exacerbate the loss of sealing member, be susceptible to leakage, it is impossible to ensure to use safety.
Summary of the invention
The technical problem to be solved is to provide a kind of direct insertion angle stop valves, simple in construction,
Conveniently opening and closing, it is not necessary to rotation valve rod, farthest decreases the loss of sealing member, adds the use longevity
Life, it is ensured that use safety.
For solving above-mentioned technical problem, the technical scheme is that
A kind of direct insertion angle stop valves, including valve body, valve rod, spool and valve gap, sets in described valve body
Having valve stem passage, intake channel and exit passageway, described valve stem passage, intake channel and exit passageway are equal
It is fixed by valve gap, in described valve stem passage, is provided with fixing cutting ferrule, described fixing cutting ferrule bottom and valve
Being provided with main spring in the first cavity that bar passage bottom is formed, described valve rod is fixed on through fixing cutting ferrule
In valve stem passage, described valve rod includes that stem body and clamping part, described stem body are cylindrical knot
Structure, described clamping part includes that head rod and clamping joint, described head rod are cylindrical structural,
Clamping joint is hemispherical dome structure, and described clamping part center is provided with the groove of " ten " font, by Access Division
Part is uniformly divided into four points, and described spool is fixed on stem body bottom by the second connecting rod, and described second
Length L1 of connecting rod, more than length L2 of described clamping part, described valve stem passage wall sets obliquely
Having four push rod passages, the outlet of described relatively low one end of push rod passage is positioned at below fixing cutting ferrule, described in push away
Slidably it is provided with push rod in bar passage, described push rod is circumferentially with a circle baffle plate, is sheathed with outside push rod
Second spring, described second spring one end is fixed in push rod passage, the other end and the baffle plate phase on push rod
Contact.
The direct insertion angle stop valves of above-mentioned one, wherein, described valve rod is sheathed with the most successively
One airtight and watertight padding, sealing ring and the second airtight and watertight padding.
The direct insertion angle stop valves of above-mentioned one, wherein, the diameter D1 of described clamping joint is more than the first connection
The diameter D2 of bar.
The invention have the benefit that
The valve rod of the present invention includes stem body and clamping part, and unique setting of clamping part makes it relative
Self-locking structure is defined for fixing cutting ferrule, when needing to close stop valve, it is only necessary to press down on valve rod,
Make clamping part slip over fixing cutting ferrule can be locked, make spool block input port passage, play closedown and make
With, meanwhile, the first spring is in compressive state due to clamping part effect；When cut-off opened by needs
During valve, pressing four push rods, the outlet of the relatively low one end of push rod passage residing for push rod is positioned at solid simultaneously
Determining below cutting ferrule, when i.e. pressing lower push-rod, push rod one end extruding clamping joint inward compression, valve rod is at the first bullet
Slipping over fixing cutting ferrule under the elastic force effect of spring to move up in situ, now spool leaves intake channel, cuts
Only valve is opened, and push rod returns in situ under the effect of the second spring compressed, simple in construction, opens
Close conveniently, good airproof performance, and whole process is without rotation valve rod, farthest decreases sealing member
Loss, adds service life, it is ensured that use safety.

Detailed description of the invention
A kind of direct insertion angle stop valves, including valve body 1, valve rod 2, spool 3 and valve gap 4,
Valve stem passage 5, intake channel 6 and exit passageway 7 it is provided with in described valve body 1, described valve stem passage 5,
Intake channel 6 and exit passageway 7 are all fixed by valve gap 4, are provided with solid in described valve stem passage 5
Determine cutting ferrule 8, set in the first cavity 9 that described fixing cutting ferrule 8 bottom and valve stem passage 5 bottom are formed
Main spring 10, described valve rod 2 is had to be fixed in valve stem passage 5 through fixing cutting ferrule 8, described valve rod 2
On be sheathed with the first airtight and watertight padding 11, sealing ring 12 and the second airtight and watertight padding 13, institute the most successively
Stating valve rod 2 and include stem body 14 and clamping part 15, described stem body 14 is cylindrical structural,
Described clamping part 15 includes that head rod 16 and clamping joint 17, described head rod 16 are circle
Column construction, clamping joint 17 is hemispherical dome structure, and described clamping part 15 center is provided with " ten " font
Groove 18, clamping part 15 is uniformly divided into four points, described spool 3 is solid by the second connecting rod 19
Being scheduled on stem body 14 bottom, length L1 of described second connecting rod 19 is more than described clamping part 15
Length L2, the diameter D1 of described clamping joint 17 is more than the diameter D2 of head rod 16, described valve
Four push rod passages 20, described push rod passage 20 relatively low it is provided with the most uniformly on bar passage 5 wall
